Hadith 4-4

نَصٌّ آخَرُ: حَدَّثَنا مُحَمَّدُ بْنُ مُوسَى بْنِ المُتَوَكِّل رَضِىَ اللهُ عَنْهُ قالَ: حَدَّثَنا عَلِىُّ بْنُ الحُسَيْنِ السَعْدْ آبادِي، عَنْ أَحْمَدِ بْنِ أَبي عَبْدِ اللَّه البَرْقِيُّ، عَنْ أَبيهِ، عَنْ خَلَفِ بْنِ حَمَّادٍ، عَنْ داوُدَ بْنِ زُرْبِي، عَنْ عَلِىِّ بْنِ يَقْطِين، قالَ: قالَ لي‏ مُوسَى بْنِ جَعْفَر عَلَيْهِ السَّلامُ اِبْتِداءً مِنْهُ: هذا أَفْقَهُ وُلْدِي - وَأَشارَ بِيَدِهِ إِلى الرِّضا عَلَيْهِ السَّلامُ - وَقَدْ نَحَلْتُهُ كُنْيَتِي.

In another tradition it is narrated that Muhammad ibn Musa ibn al-Mutawakkil - may God be pleased with him - narrated that Ali ibn Al-Husayn As-Sa’dabadi quoted on the authority of Ahmad ibn Abi Abdullah al-Barqi, on the authority of his father, on the authority of Dawood ibn Zorbi, on the authority of Ali ibn Yaqteen, “Musa ibn Ja'far (a.s.) told me - without me having said anything to him, ‘This is my most knowledgeable child. I have placed my nickname on him.’ He pointed to Al-Ridha’ (a.s.) with his hand.”
